Whether primary and secondary growth can occur simultaneously in the same plant. Concept introduction : Plants have the unique ability to grow throughout their life unlike animals. This type of growth is known as indeterminate growth. Plants possess undifferentiated tissues known as the meristem. Meristem tissues contain cells that have the ability to divide and produce new cells. These new cells elongate and differentiate to form the different parts of plant. Some plant organs do not show growth throughout their life. They stop their growth after a period of time. Primary growth refers to the growth that occurs in length. The primary growth is mainly due to apical meristem. The apical meristem is found in apical parts of shoot and root. It allows root to grow under the soil and shoot to grow upward to increase the sunlight exposure. Secondary growth refers to growth in thickness. It occurs due to the lateral meristem. The lateral meristem includes vascular cambium and cork cambium. The secondary growth occurs in those parts in which the primary growth has been stopped.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
